Specification of Letters Patent.

Patented July 2%, 1917.

Application filed January 5, 1917. Serial No. 140,716.

To all whom it may concern:

Be it known that I, FRANK KRZYSKO, a citizen of the United States,residing at Amsterdam, county of Montgomery, and State of New York, haveinvented certain new and useful Improvements in Tube-RectifyingMachines, of which the following is a specification.

Reference may be had to the accompanying drawing, and the referencecharacters marked thereon, which form a part of this specification.Similar characters refer to similar parts in the several figurestherein.

In the weaving of Axminster fabrics, the strands of filling-yarn as theypass from the roll-are led through a number of small tubes, whereby theyarns of different colors are guided and presented to the loom-mechanismin proper relative position for incorporation into the fabric.

These tubes are made of thin sheet-metal such as tin, and are mountedside by side upon a supporting-frame, from which the tubes projectaconsiderable distance separately and unsupported.

The tubes sufi'er frequent injury in use and in transportation to andfrom the looms, and require to be constantly rectified or renewed inorder to insure their proper operation. V

The rectifying of such tubes has heretofore been done largely by hand,requiring the careful insertion of a punch through the several tubes tostraighten them and restore them to propercross-sectional form; but inrectifying tubes by hand as heretofore practised, the tubes have notbeen properly exteriorly supported to cooperate with the inserted punch,so that the results have been more or less crude.

In such attempts as have been made to rectify such tubes by machine theoperation has been slow and tedious, permitting the operation of themachine upon only part of the tubes of the frame at one time, anddepending largely upon the operator for the manual operation of thevarious devices to successively act upon the tubes.

The principal objects of the present invention are to facilitate therectifying of such tubes; to rectify the tubes automati-' cally withoutparticular attention of the operator of the machine to the successiverectifying operations; to properly support the tubes during theOperation of the machine;

to simultaneously rectify the tubes of an entire frame; and to secure amore uniform and perfect rectifying of the tubes.

Other objects will appear in connection with the following description.

Referring to the drawings wherein the invention is shown in preferredform, 1 is the frame of the machine, having supports, 2, for theopposite ends of a tube-frame, 3, having .numerous tubes, 4, mountedthereupon. Abutments, 5, form stops against which the frame is forced bya plurality of cams, 6, pivotally mounted at 7, upon a frame, 8, infixed relation to the frame of the machine.

The cams, 6, are simultaneously operated by means of a T-frame, 9, thehead, 10, of which is pivotally connected at 11, with the respectivearms, 12, on the cams.

The body of the T-fraxne, 9, is adapted to frame, 8.

V ;ot er end of the swaging-platebeing pro-v A pair of diagonal links,16, are pivotally connected at 80, together and to the body of theT-frame,.i9, and at their other ends they are pivotally connected to therespective cam-arms, .12, whereby said cams are. oper ated in unison.

- When the tube-frame is mounted in the machine, its tubes, 4, overlieand rest upon a swaging-plate, 17, which is adapted to recipro'catelongitudinally along a path extendlng transversely of the row of tubes,4.

This swagingplate is adapted to be reciprocated by means of a lever, 18,having its upperhe'n'd, 19, loosely fitting an aperture, '20 in one endof the swaging-plate, the

vided with a longitudinal guide-slot, 21, through which extends aguide-finger, 22, fixed upon the frame of the machine.

The 'lever,'18, is pivoted at 23 upon the frame'of the machine, and hasupon its other end a cam-follower, 24, adapted to'be engaged by acam,25, fixed upon a. shaft, 26, rotatively mounted in bearings upon theframe of the machine.

The shaft, 26, is operated through a train of gears 27, 28,29 and 30,from a clutchdriven shaft, 31, which has non-rotatively mounted thereon,and slidable longitudinally thereof, one member, 32, of a clutch.

The complementary clutch-member, 33, is fixed upon a gear-wheel, 34,both being rotatively mounted upon the shaft, 31, with said gear-wheel,34, in enga emcnt with a pinion, 35, fixed upon a 'mam drive-shaft, 36,carrying a pulley, 37, adapted to receive a driving-belt, not shown. Theclutch-member, 32, is operated to engage the clutch-member, 33, by meansof an angle-lever, 38, fulcrumed at 39, upon the frame of the machine,the lower member of which angle-lever is engagedby an arm, 40, of 'afoot-operated lever, 41, fulcrumed at 42, upon the frame of the machine.

A series of mandrels, 43, is mounted upon a slide-carriage, 44, m0vablealong slideways, 45, longitudinally of the machine parallel with thetubes, 4, with thema'ndrels in line with the res ective tube-openingswhen the tube-frame 1s machine. 1 1

. The slide-carriage, 44, has on its upper side a longitudinal flan e orrib, 75, formed with grooved seats, 76, or the shanks of the respectivemandrels, whichv shanks are notched-at 77 on their underside to makeinterlocking engagement with the respective grooved seats, as shown inFig. 12. The

shanks of the mandrels are held to their properly placed in the lowerendrof which link is pivotally' connected at 49 with the frame of themachine- A connecting-rod, 50, connects an intermediate portion of eachlink, 46, with a crank-disk, 51, said crank-disks being fixed upon theopposite ends of ashaft, 52, rotatively mounted in bearings on the frameof the machine, and upon which shaft, 52, is fixed the gear-wheel, 28.

A swaging-bar, 53, is'rockingly mounted by means of trunnions, 54, uponand between a pair of levers, 55, fulcrumed upon a shaft, 56, mounted ina pair of slide-bearing-blocks, 57 reciprocatory along respectiveslideways, 58, longitudinally of the machine.

Each of said levers, 55, is pivotally connected at 59 with the upper endof a link, 60, the lower end of which link is pivotally connected at 61with the frame of the machine.

Each of the levers, 55, is connected by a connecting-rod, 62, with "acrank-disk, 63, said crank-disks being fixed. upon the opposite ends ofthe shaft, 26;

The under surfaceof the swaging-bar, 53,

is grooved or toothed, asshown at 66, to

form a matrix for the respective tubes, 4,

complementary to the respective mandrels, 43.

swaging-bar, 53, are at certain times supported in elevated position, asshown in Fig. 1, by means of a pair of bars, 67, each verticallyreciprocatory in a slideway-bracket, 68, at the respective side of themachine, and each pivotally connected at its lower end with a crank-pin,69, on a crank-disk, 64, said crank-disks being fixed upon the oppositeends of a shaft, 65, rotatively mounted in hearings on the frame of themachine, and having fixed thereon a gear-wheel, 86, mesh ing with thegear-wheel, 27.

As the crank-disks, 64, are rotated, the bars, 67, are raised andlowered in their respective slideways, 68.

The'upper end of each bar, 67, is forked, one branch thereof, 70,engaging the under side of the neighboring lever, 55, while, its otherbranch, 71, is connected with the corresponding branch of the bar, 67,on the other sideof the machine by means of a guide-plate, 72, which mayhave graduations marked thereon, as shown in Fig. 3, to assist theoperator in accurately locating the tubeframe, so that the tubes, 4,will be properly alined with the respective mandrels, 43.

Coil-springs, 73, connecting the respective bars, 67, with the frame ofthe machine, tend to draw the upper ends of the bars forward to bringthe plate, 72, closely adjacent to the ends of the tubes, 4.

The swaging-plate, 17, is slightly tapered in cross-section, as shown inFig. 8, the thicker edge of said plate being adjacent to the outer endsof the tubes, 4, causing said plate to actmore eflectively upon saidtubes near their outer ends.

The thicker edge of the swaging-plate is also preferably made in theform of a series of teeth, 74, which are slightly beveled on the sidewhich engages the tubes, causing them to operate with a wedging actionto swage the tubes into proper form.

The operation of the machine is as follows: I

The tube frame having been placed in the machine in the position shownin Fig. 3, and clamped in such position by means of the cams, 6, themachine is started by pressing down upon the foot-lever, 41, causing theclutch-member, 32, to engage the clutchmember, 33, thus setting inoperation the several shafts, 26, 52, and 65. A rearward movement isthus imparted to the slide-carriage, 44, causing the mandrels, 43, toenter the respective tubes, 4, expanding to full size any which may havebeen indented or bent inward, and approximately straightening any whichmay have been bent out of alinement. The tube-engaging portion of eachmandrel, 43, is of the cross-sectional form of the interior of a perfecttube.

As the mandrels approach the limit of their rearward movement throughthe tubes, the swaging-bar, 53, will have been carried forward from theposition shown by solid lines to that indicated by dotted lines in Fig.1, which movement is the resultant of the forward movement of theslide-bearingblocks, 57, and the lifting action of the arm, 70, of thebar, 67.

As the swagin -bar, 53, reaches its forward position the ars, 67, arecarried downward by the crank-pins, 69, and the swaging-bar, 53,ispermitted to descend into engagement with the upper sides of thetubes, 4, causing the convergent upper sides of the respective tubes toepressed into shape between the respective mandrels, 43, and the groovedportions, 66, ol the swaging-bar,

which'acts as a complementary matrix to the mandrels.

During the first part of the return movement of the slide-bar, 57, theswaging-bar,

53, is, drawn rearward along the tubes;

swaging them into proper form upon their respective mandrels by asliding or ironing action.

While the swaging-bar, 53,is in engagement with thetubes, 1t serves tohold them down upon the swaging-plate, 17, while the same is slidlongitudinally from one side to the other of the machine by means of thelever, 18, which movement causes the bottoms of the tubes to be pressedbetween the swagingplate, '17, and the bottoms of the respectivemandrels, 43, while said swaging-plate is moving in a direction to causeits beveled teeth, 74, to engage the bottoms of the tubes with a wedgingaction.

During the operation of the machine upon the tubes, each tube issupported on all sides of its interior by one of the mandrels, 43, whileall sides of its exterior are being operated upon by the swaging-plate,17, and swagin -bar, 53, thus causing the tubes to .be rectified notonly as to alinement, but as to cross-sectional form as well.

A. coil-spring, 81, connecting the lower arm of the lever, 38, with theframe of the machine tends to disengage the clutch-memher, 32, from theclutch-member, 33.

Fixed upon the shaft, 42, which forms the fulcrum for the lever, 41, isa rocker-arm, 82, carrying a cam-follower, 83,'engageable with a cam,84, fixed on the shaft, 31.

This cam, 84, is of general circular form having a notch or recess at 85to receive the cam-follower.

After the machine has been set in opera tion by depressing thefoot-lever, 41, the foot ofthe operator can be removed and the machineaftercompleting the cycle of operations above described will beautomatically stopped by disengagement ot the clutchmembers due to theaction of the spring, 81, when the cam-follower, 83, enters the notch,85, in the cam, 84.
